Abstract

1485593 Polymers of 2-acrylamido-2-methylpropane sulphonates FUJI PHOTO FILM CO Ltd 25 Nov 1975 [26 Nov 1974] 48292/75 Heading C3P [Also in Division G2] Polymers for use as flocculating agents for photographic gelatino silver halide emulsion comprise a homopolymer of the Formula I wherein M represents H, Li, Na, K or (wherein R<SP>1</SP>, R<SP>2</SP> and R<SP>3</SP> each represent a hydrogen atom or an alkyl group containing up to 5 carbon atoms, the sum of the carbon atoms in R<SP>1</SP>, R<SP>2</SP> and R<SP>3</SP> being not more than 10), or a copolymer of the compound of Formula I with certain defined co-monomers. Examples are given of the homo-polymerization of potassium 2 - acrylamido - 2 - methylpropanesulphonate, and of the copolymerization of that monomer with acryloylmorpholine.
